Premium LED Bulb Automotive Circuit Tester, 6-24V Test Light with 135 Inch PU Extended Spring Wire, Sharp Hard Steel Probe Vehicle Circuits Low DC Voltage Light Tester

This circuit tester appears to be a reliable and affordable tool for general automotive electrical diagnostics. It offers good value for its price and I love its ease of use and bright LED indicator. I personally upgraded from a rather old flashlight bulb type. However, users should be mindful of the potential for wire damage due to the sharp probe and the sometimes stiff clamp.If you are looking for a basic circuit tester to keep in your toolbox for everyday automotive electrical checks, this seems like a solid option. Pros:Easy to use and understand: Simple connection makes it user-friendly for both beginners and experienced individuals.Effective for troubleshooting, it effectively checks for continuity and helps pinpoint electrical issues.Bright LED light, The high-visibility LED bulb makes it easy to see when a circuit is live.Long and flexible wire: The extended spring wire provides ample reach.Durable construction: Seems well-built and sturdy.Good value for the money a worthwhile purchase. Cons:Limited Voltage Range: Only suitable for testing circuits within the 6-24V DC range.Potential for wire damage. The sharp probe requires careful use to avoid damaging delicate wires.Clamp stiffness: the clamp is a bit stiff and difficult to open, especially on circular surfaces. Springy cord can be inconvenient, The coiled wire can be a bit too springy, potentially pulling the clip off if not properly secured.

Great price and solidly built. Comes with an extra led and that concerns me as to why they think a led is gonna go bad. But for this price you can’t go wrong.

Works great. Built well and very easy to use.

I had a 20 year old tester that finally kicked the bucket. I ordered this to troubleshoot trailer lighting on my jeep. I was fairly impressed with the quality of this!

Superb. Bright light, easy to use, worked every time to confirm continuity of the circuits.

Works great . The clip really holds onto ground or power.

So basically the tool works as any circuit tester. Bought this because the one I had was stolen unintentionally basically.Anyway, the cord is really springy and so is that alligator clip. That clip holds on for dear life man. Kind of sucks if it's a circular shaft that you're connecting to though as it grips so damn hard that it slips off if that makes sense.Also, the cord is pretty long, but if you're gripping on a bolt head, the springiness of the cord is so... Uh... Slinky like that it'll pull the clip off and whip you.That being said, if the clip can grip properly onto something. Good luck pulling that off. Can be pretty hard to open the clip because of how strong that is, so, don't bite anyone's ear with it or anything.
